VEHICLE VENTILATOR.

Application led May 13, 1922. Serial No. 560,624.

To all whom -z't may concern- Be it known that I, Jnoon GABOR, a subjectof the King of Roumania, and resident of the city of New York, boroughof Brooklyn, county of Kings,` and State of New York, have invented anew and Improved Vehicle Ventilator, of which the following is a full,clear, and exact description.

My invention relates to a ventilator, and aims to provide a device ofthis nature particularly adapted for use in association with a vehicle,such asa motor car, although it is' not necessarily limited to use inthis connection.

It is an object of the present invention to provide a ventilatorparticularly adapted for association witha closed motor vehicle, andwhich will-present an extremely neat appearance, and which will further'serve to ventilate the interior of the same.

Still another object of this invention is that of manufacturing aventilator capable of being constructed at a nominal figure, and whichwill prevent the entrance of rain, snow, etc., into the space with whichit is connected.

In the annexed drawings a practical embodiment of my invention isillustrated, and it will be seen that;

Figure 1 is a sectional side view of a ventilator embodying my improvedconstruction and showing the same associated with the wall of acompartment which is to be ventilated.

Figure 2 is a transverse sectional view of the said ventilator and takenalong the line 2 2 and in the direction of the arrows indicated inFigure 1.

F figure 3 is a sectional plan view` taken along the line 3-3 and in thedirection of the arrows also indicated in Figure 1, and

Figure 4 is a side elevation of one portion of the ventilator assembly.

Referring to Figure 1 it will be noted that the reference numeral 5indicates the support for the ventilator, which support may be therool:l of a vehicle.

Associated with the support is my improved type of ventilator which inthe embodiment illustrated includes 2 body portions detachablyassociated with each other, one of the same being disposed above thesupport while the second of the same is arranged below the same.

The tirst of these bodies is shown for the sake of illustration ascomprising a ared tube 6 which preferably has the lower portion of itsbody arranged parallel to the supporting surface 5, it being furtherunderstood that the larger end of this tube conveniently extendsforwardly, while the smaller end of the same extends rearward# ly.Exten-ding into this tube and project# ing rearwardly therein is a pipe7 presenting an open end, and it will be obvio-us, assuming that air isblown through the tube 6 in the direction indicated bythe arrow inFigure 1, that this air will blow past the pipe 7 and cause a suction tobe exerted upon the open end of the same resulting in air being drawnthrough its body and discharged from the rear end of the tube 6.

With a -view of preventing the entrance of rain, etc., into theventilator, a fiapy valve may be swingably attached to the rear end ofthe tube 6 as at 8 and includes a body 9 which may be counter-balancedby a weight 10. Incident to the weight of the body 9 it will beunderstood that the valve will normally be closed and guard against anyflow of Huid into the rear of the tube 6 or the entrance of rain, etc.,at this point. However upon the vehicle, or other member with which theventilator is associated, movin forwardly, the flow of air into theforwar end of the tube will result in the valve being opened to theposition indicated in dotted lines in Figure 1, thus causing a suctionas aforedescribed, to be exerted upon the pipe 7 Due to this action, inaddition to guarding against the entrance of the elements through thebody of the ventilator, it will be seen that any danger of air beingintroduced into the same upon the vehicle backing, or from other causes,will be eliminated.

Now with respect to the second major portion of the ventilator and whichconstitutes the present invention, it will be noted, reference beingparticularly had to Fi ures 3 and 4;, that this portion may inclu eessentially a pair of casings 11 and 12 rotatably secured together byany suitable means, such as a pin 13, these casings being of such a sizethat one of the same may nest within the other. Both of these casingsare formed with openings 14 which may be brought into alignment witheach other by rotating the innermost casing 11 with respect to theoutermost casin 12 by any suitable means, such as a hand e'15.

Now with a view of connecting the major portions of the ventilator, onewith another, it will be seen that the casing 12 has a collar 16associated with it, this collar being formed with exterior screwthreads, which enga-ge with interior screw threads' forming a part ofthe pipe 7 as has been indicated at 17. A plurality of washers 18 ot'any suitable material may also be interposed between the upper portionof the ventilator and the upper surface of the support 5, andv thus uponthe parts being' tightened through the medium of the screws, any leakagethrough the opening provided in the support 5 is prevented. l

Thus all of the objects of this invention have been accomplished, and itWill further be appreciated that numerous modifications of structuremight readily be resorted to Without in the least departing from the scoe of my claim; which is: l

n a ventilator for use with vehicles, a pair of nesting casings arrangedwithin the vehicle, each casing including an annular vertical wallhaving openings and a bottom Wall having openings, the bottom wallsbeing pivotally connected at their centers, the outer casing beingsupported upon the vehicle, the inner casing being rotatably supportedwithin the outer casing, -the openings in said casings being adapted tobe brought'into registry or moved out of registry upon rotation of thecasing.

JACOB GABOR.
